"SLATY GUM." BATCH n (INCLUDING MOUE on LESS E. Daicsonl). 
" Slaty Gum of the Mudgee district." Cobborah ( District Forester Marriott). 
" Red Box," Reedy Creek, near Gulgong. "Narrow leaves; big tree, glaucous 
all over" ( J. L. Boorman). " Slaty Gum," Reedy Creek. " Fine large trees growing 
on slight ridges away from the creek : at this period (April) of the year the stems 
are pure white with irregular patches of green ; the bark is ] inch thick, falling away 
in long ribbons ; the leaves and tips of branches are of mealy whiteness. Sapwood 
pale yellow, centre red " (J. L. Boorman). " Red Box," Gulgong. "The whole of 
the tree of a silvery whiteness." A second specimen with leaves from lanceolate to 
ovate (J. L. Boorman). 
"Red Box" or "Slaty Gum," rarely called " Bastard Box," Gulgong. 
"Leaves on shoots from nearly orbicular to nearly linear lanceolate " (J.II.M. and 
J. L. Boorman). 
"Slaty Gum" is considered the best in the district (Mudgee), but unfor- 
tunately the supply is not equal to the demand. Grows in the district west of Reedy 
Creek. Used for all work where toughness is required. Differs from Ironbark, 
inasmuch as the log when drying at the butt cracks in rings, while Ironbark radiates 
from the centre" (Forest Ranger Marriott). 
Mr. A. G. Hamilton (Proc. Linn. Soc. N.S.W., xii, 277) states that the 
" Slaty Gum " is common on the ridges at Mudgee, where it does not attain a 
great size, but on the flats at Tallewang it runs up into splendid trunks, which are 
much used in bridge building, &c., and the timber is considered very durable. 
" Slaty Gum," Bylong Creek, typical for E. Daicsoni (R, T. Baker). 
"Red Box," " Mountain Gum," Murrumbo, Goulburn River; Camboon ; 
Bylong (R. T. Baker.) Three specimens showing transition from lanceolate leaves 
to ovate." Denman (R. n. Cambage). 
" Slaty Gum." Type localities for E. Daicsoni arc ridges on the watershed 
of the Goulburn River (R.T.B.) ; across the Main " Divide " at " Cassilis, and 
north-west of Pilliga " (Professor Warren). 
I suggest that Slaty Gum is a large, erect Red Box grown under favourable 
circumstances. Accompanied by a collector, Mr. J. L. Boorman, I made careful 
observations. Then I sent Mr. Boorman alone to carefully investigate the trees, 
and he performed his duty in an intelligent manner. Although satisfied with his 
reports, I went again into the field with him, and the three trips resulted in the 
accumulation of a large and varied quantity of botanical material, including timber 
and bark. I found people indifferent as to the uss of the names " Slaty Gum or 
1 1 <! Box," applying them indiscriminately as a very general rule. More than one 
timber worker told me they were the same tree, and all the evidence I accumulated 
points in the same direction. As the confusion in regard to " Red Box and Slaty
